AlienAdrenaline
Launch games your way with personalized shortcuts in Game Mode, maximize performance with the new Accelerator feature, and keep an eye on resource consumption with Performance Monitoring.

Game Mode: Stay one step ahead of the competition. Game Mode gives you the ability to customize how your game or application launches — including what AlienFX theme to implement, what VOIP to use for a specific game and what web pages or applications you want opened or closed when the game launches and more.

Accelerator: AlienAdrenaline’s Accelerator is an instant performance booster. It ends process trees for Windows-based applications and services that are unnecessary, giving your system a boost in speed. It won’t permanently alter your system’s configuration, or uninstall any software or programs. It merely sheds some weight temporarily and then returns to its original state once you’re done gaming.

Performance Monitoring: AlienAdrenaline’s Performance Monitoring tool provides a graphical representation of hard drive, system memory, network, processor and graphics card usage, so you can track system performance and identify problems while playing a game or running resource-intensive applications. Monitor your performance in real-time or record and review them later.

AlienFX system lighting
Create custom lighting to suit your unique gaming style. Apply 20 different colors to 3 different zones for up to for 8,000 color combinations.

Themes: Create your own custom lighting for a truly unique and personalized look. AlienFX lets you create, edit and save your own custom themes. Or select from several preset themes already available on Alienware systems.

AlienFusion
Access your system’s power-management controls so you can decide when you need maximum performance or when to scale back for more everyday programs.

Quick settings: Get easy access to preset power options like high performance, balanced or power saving modes. Quick settings is an easy interface to fine-tune those settings.

Advanced settings: AlienFusion’s advanced settings mode gives you control over how you want individual components in your system to behave while running on specific power modes — like adjusting the behavior of your wireless adapter or graphics processor.

Custom power plans: Create unlimited power plans to suit every different need. Optimize gameplay for any specific online game you play, then save and modify your custom power plan in the AlienFusion interface.
